I'm pretty much the exact same way. The only thing that works for me is simply embracing it. Considerable unemployment times has shown that my natural circadian rhythm is from 7am to 2pm, give or take, meaning that all those extra 4 or 5 hours are really not sleep at all, but just some state of not-sleep. Adjusting this to normal working hours is rather difficult, but I've simply accepted the fact that there is no shame in being tired, so if I have to sleep at 6pm, just fall into bed and sleep. Of course, I don't have kids and I don't feel like I'm missing out on life if I don't go out on Friday night.
